Blockchain enabled vehicular networks: a review

Vehicular network is an emerging and advanced component in the field of transportation systems. In vehicular network, all authenticated vehicles can communicate with each other and with other components of the network. This is done to ensure the security of the information shared among vehicles. The information may contain sensitive data like speed of vehicle, vehicle's identity, and current position of vehicle. Vehicular network provides various different advantages to drivers but at the time it is susceptible to privacy and security attacks. It is essential to address various security and privacy issues. Existing possible solutions are not feasible for providing security in the vehicular network. Therefore, blockchain has been introduced in the vehicular network that provides decentralized platform which is capable of managing and handling resources. Further, it resists various security attacks that may occur in the network. This paper provides the review of blockchain-based vehicular network and discusses the various schemes used by different authors involving blockchain in vehicular networks.
